GiveN :-

  • Length of AB = 10 cm
  • Length of AD = 8 cm
  • Length of AC = 17 cm

To FinD :-

  • Length of BC

SolutioN :-

By using Pythagoras theorem

In ∆ ABD

BD² + AD² = AB²

→ BD² + 8² = 10²

→ BD² = 100 - 64

→ BD = √36

→ BD = 6 cm

In ∆ ADC

DC² + AD² = AC²

→ DC² + 8² = 17²

→ DC² = 289 - 64

→ DC = √225

→ DC = 15 cm

BC = BD + DC

→ BC = 6 + 15

→ BC = 21 cm
